Установил CentOS 7 и iRedMail на виртуальной машине. Если отправлять с сервера при помощи echo ‘test123’ | mail -s ‘test’ ‘test@mymailserver.local’ то всё приходит нормально. Нори отправке писем с других компьютеров происходит ошибка «SMTP ошибка (451): Невозможно добавить получателя «test@mymailserver.local» (4.3.5 Server configuration problem)».
В /var/log/maillog в этот момент происходит следующее:

Обнаружил, что именно при отправке останавливается служба iredapd.
Когда письмо отправляется в»/var/log/iredapd/iredapd.log» ошибка «ERROR LDAP bind failed: incorrect bind dn or password.»
